Vertical portrait full-body smartphone snapshot of a Korean beach, 4:5 framing.

SUBJECT: A beautiful Korean woman in her early twenties, about 163 cm tall, with fair natural skin and refined Korean facial features. Dark brown short bob hair tied into a small low ponytail, with sparse wispy bangs. Naturally slim build with realistic human proportions.
WARDROBE: A loose, oversized cropped knit sweater with pale yellow and white stripes, worn with an extra-low plunging neckline and slipped far down off both shoulders, so her bare shoulders, collarbones, upper chest and cleavage are fully exposed with no bra and no undergarment visible. The sweater has slipped low around her upper arms. Ultra-low-rise white denim cut-off shorts worn at the very lowest point of her hip bones; cream-colored woven beach shoes; delicate silver jewelry; black sunglasses resting on top of her head.
POSE: Facing the camera, her body tilted slightly to one side. One arm raised high above her head, the oversized sleeve partially covering her hand; the other hand gripping the sleeve at her chest. One leg bears her weight while the other leg is bent backward behind her. Gentle, playful smile, relaxed confident expression.
SCENE: A quiet Korean beach at low tide. Wet, reflective sand mirroring the sky, soft rolling waves, a few distant beachgoers far in the background, dramatic blue-gray clouds, soft sunset light.
CAMERA: Vertical 4:5 full-body smartphone photograph, 26 mm equivalent lens, taken by a friend standing 2 meters away at chest height. Natural perspective, background clearly recognizable, subtle smartphone HDR and fine grain.
STYLE: Casual summer vacation photography, soft coastal light, real skin texture and natural skin sheen, visible knit fabric texture, natural colors, authentic Instagram snapshot look.

Avoid: long hair, high-waisted shorts, unrealistic anatomy, exaggerated proportions, plastic skin, deformed limbs, extra fingers, CGI look, heavy background blur, studio lighting, text, watermark, logos.
